The
exchange
between
Sam
Altman
and
Elon
Musk
on
X
reflects
their
evolving
views
on
Donald
Trump.
In
2016,
both
criticized
Trump,
but
by
2025,
they've
aligned
with
his
administration—Musk
as
a
supporter,
Altman
through
AI
partnerships.
Their
posts
seem
less
about
"slinging
mud"
so
excited
that
is
joining
openai
in
a
new
role:
ceo
of
applications,
reporting
to
me.
i'll
remain
ceo
of
openai,
but
in
this
new
configuration
i'll
be
able
to
increase
my
focus
on
research,
compute,
and
safety.
these
are
critical
as
we
approach
superintelligence.
fidji
is
exceptional;
we
have
worked
together
on
openai
for
the
past
year
and
i
have
observed
her
deep
commitment
to
our
mission.
i
cannot
imagine
a
better
new
team
member
to
help
us
scale
the
next
10x
(or
100x,
let's
see).
great
to
see
progress
on
the
first
stargate
in
abilene
with
our
partners
at
oracle
today.
will
be
the
biggest
ai
training
facility
in
the
world.
the
scale,
speed,
and
skill
of
the
people
building
this
is
awesome.
this
is
much
less
important
than
tweeting
about
agi,
but
it
is
nevertheless
amazing
to
me
that
the
entire
venture
industry
can
(in
aggregate)
lose
money
for
so
long
and
keep
getting
funded.
i
am
very
curious
why
LPs
do
it.
(obviously
if
you
can
fund
the
top
funds
you
should!)
this
has
been
one
of
my
helicopter
moments
too:
very
grateful
to
all
the
developers
who
spent
time
with
us
telling
us
what
they
wanted
from
an
open-weights
model.
the
feedback
was
useful
and
unexpected,
but
all
doable.
i
think
we
will
ship
something
extraordinary!
today
we
launch
deep
research,
our
next
agent.
this
is
like
a
superpower;
experts
on
demand!
it
can
go
use
the
internet,
do
complex
research
and
reasoning,
and
give
you
back
a
report.
it
is
really
good,
and
can
do
tasks
that
would
take
hours/days
and
cost
hundreds
of
dollars.
people
will
post
lots
of
great
examples,
but
here
is
a
fun
one:
i
am
in
japan
right
now
and
looking
for
an
old
NSX.
i
spent
hours
searching
unsuccessfully
for
the
perfect
one.
i
was
about
to
give
up
and
deep
research
just...found
it.
i
have
been
on
a
shopping

this
morning,
this
is
much
better
than

We’ve
spent
the
last
few
days
doing
a
deep
dive
on
what
went
wrong
with
last
week’s
GPT-4o
update
in
ChatGPT.
Expanding
on
what
we
missed
with
sycophancy
and
the
changes
we’re
going
to
make
in
the

openai.com/index/expandin
goodbye,
GPT-4.
you
kicked
off
a
revolution.
we
will
proudly
keep
your
weights
on
a
special
hard
drive
to
give
to
some
historians
in
the
future.
the
last
couple
of
GPT-4o
updates
have
made
the
personality
too
sycophant-y
and
annoying
(even
though
there
are
some
very
good
parts
of
it),
and
we
are
working
on
fixes
asap,
some
today
and
some
this
week.
at
some
point
will
share
our
learnings
from
this,
it's
been
interesting.
we
started
rolling
back
the
latest
update
to
GPT-4o
last
night
it's
now
100%
rolled
back
for
free
users
and
we'll
update
again
when
it's
finished
for
paid
users,
hopefully
later
today
we're
working
on
additional
fixes
to
model
personality
and
will
share
more
in
the
coming
days
a
few
things
are
different
about
the
api
version
than
the
chatgpt
version:
you
can
control
moderation
sensitivity
with
the
'moderation'
parameter
you
can
also
control
things
like
quality
vs
generation
speed,
background,
output
format,
etc.
we
have
doubled
rate
limits
for
o3
and
o4-mini-high
for
chatgpt
plus
subscribers.
enjoy!
Replying
to
we
really
do
try
to
listen
to
feedback!
we
would
love
to
be
able
to
do
even
more;
we
continue
to
have
to
make
very
hard
tradeoffs
between
rate
limits,
new
feature
launches,
and
latency.
the
GPUs
are
coming,
so
hopefully
it
gets
better.
deploying
fusion
to
the
world
is
surprisingly
gated
on
high-power
semiconductors.
the
most
important
place
you
could
design
and
build
those
high-power
semiconductors
(and
do
other
awesome
electrical
engineering)
is
helion.

your

you

will
have
something
like
10/month
in
our
plus
tier
and
a
very
small
number
in
our
plus
tier,
but
we
are
working
on
a
more
efficient
version.
(this
version
is
built
on
o3.)
I
can
finally
reveal
that
I’ve
had
early
access
to
’s
Deep
Research
since
Friday
&
I’ve
been
using
it
nonstop!
It’s
an
absolute
game-changer
for
scientific
research,
publishing,
legal
documents,
medicine,
education-from
my
tests
but
likely
many
others.
I’m
just
blown
away!
congrats
to
the
team,
especially
and
,
for
building
an
incredible
product.
my
very
approximate
vibe
is
that
it
can
do
a
single-digit
percentage
of
all
economically
valuable
tasks
in
the
world,
which
is
a
wild
milestone.
way
back
on
friday,
the
high
score
on
"humanity's
last
exam"
was
o3-mini-high
at
13%.
now
on
sunday,
deep
research
gets
26.6%.
Replying
to
give
it
a
try
on
your
hardest
work
task
that
can
be
solved
just
by
using
the
internet
and
see
what
happens.
got
one
more
o3-mini
goody
coming
for
you
soon--i
think
we
saved
the
best
for
last!
soon
we
will
need
another
exam...
o3-mini-high
is
really
good
and
it's
cool
to
hear
some
people
say
it's
their
favorite
model
ever
but
it
reminds
me
of
when
we
used
to
have
something
internally
called
"the
little
big
run"
a
top
2025
goal
is
to
fix
our
naming

especially
worth
noting

harder
and

a
lot
of
people
prefer
this
to
o1,
and
it's
just
the
mini
model.
now
we
work
on
the

why
not

today.
the
machine
is
making
rapid
progress
(and
the
scale
is
nuts)--it
feels
like
walking
through
a
sci-fi
movie!
next
phase
of
the
msft
x
oai
partnership
is
gonna
be
much
better
than
anyone
is
ready
for!!
